[0009]

By the way, in recent years, recycling activities have been actively promoted around the world in order to solve the shortage of resources, and equipment having excellent decomposability is strongly desired in the market. From such a viewpoint, the substrate 14 and the bundle fixing members 16 and 24 may be reused. In this case, the bundle fixing members 16 and 24 are removed from the substrate 14.
However, the hooking portions 20 and 28 of the two types of bundle fixing members 16 and 24 are very hard to come off because they are inserted into the holes 14 a of the substrate 14. Therefore, the bundle fixing member 1
In order to remove the substrates 6, 24 from the substrate 14, the hooks 20, 28 must be picked from the back side of the substrate 14 and pulled out from the hole 14a. This operation is troublesome and troublesome.

For this reason, it is often the case that the hook portions 20, 28 are cut from the back side of the substrate 14 using a tool such as a nipper, and the bundle fixing members 16, 24 are removed from the substrate 14.
However, the operation of using such tools such as nippers is also a troublesome operation, and the bundle fixing members 16 and 24 from which the hook portions 20 and 28 have been cut cannot be reused. .

In view of the above circumstances, it is an object of the present invention to provide a bundle fixing member which can be easily attached to and detached from a substrate or the like and has excellent recyclability.

A hook portion 52 is inserted into the hole 60a and hooked on the hole 60b. The structure of the wire saddle is the same as the conventional one. The hook portion 52 has a circular cross section that becomes thinner toward the tip (lower end).
The bundle fixing member 50 is a flexible plate (not shown, but a flexible plate 36, which is configured to bend according to the thickness of the substrate 60.
It has the same structure as the above).

The upper diameter φd1 of the hook portion 52 is
It is smaller than the diameter φD1 of the hole 60b. Further, the maximum shape φd2 of the hook portion 52 is smaller than the diameter φD2 of the hole 60a. Further, the upper width L5 of the hook portion 52 is
The width is slightly smaller than the width L6 of the communication hole between the hole 60a and the hole 60b.

In fixing the bundle 10 (see FIG. 2) to the substrate 60, first, as shown in FIG. (In the vertical direction) and the hook portion 52 is inserted into the hole 60a. After the hook portion 52 is completely inserted into the hole 60a, the bundle fixing member 50 is slid in the direction of arrow D (the horizontal direction in the present invention) to hook the hook portion 52 in the hole 60b. Thereafter, the hook 52 is rotated by about 90 ° in the direction of arrow E (the horizontal direction in the present invention).

Arrows, numerals, and the like indicating the procedure for removing and disassembling 0 (see FIG. 1) from the substrate 40 are drawn near the hole 40a of the substrate 40. Therefore, even if there is no instruction or the like, the substrate 40
The bundle fixing member 30 can be easily removed from the cable. As a result,
The recyclability of the bundle fixing member 30 is further improved.

[0032]

As described above, according to the bundle fixing member of the present invention, when the bundle is fixed to the fixing surface,
Since the bundle fixing member cannot be removed in the vertical direction of the fixing surface,
The bundle fixing member does not come off easily. By pulling out the bundle fixing member in a direction perpendicular to the fixing surface, the bundle can be removed from the fixing surface. Since the bundle fixing member is easily attached to and detached from the fixing surface, a bundle fixing member excellent in recyclability can be obtained.

Here, when the bundle fixing member is rotated in the horizontal direction of the fixing surface and is detachable from the fixing surface, the bundle fixing member is detached by rotating the bundle fixing member in the horizontal direction of the fixing surface. Therefore, a bundle fixing member with more excellent recyclability can be obtained.

When the bundle fixing member is detachable from the fixing surface by rotating and sliding the fixing surface in the horizontal direction, the bundle fixing member is moved from the fixing surface by rotation and sliding. Since it is attached and detached, a bundle fixing member that does not easily fall off from the fixing surface when fixed to the fixing surface is obtained.

Further, when the bundle fixing member is to be attached to and detached from the fixing surface on which information indicating the disassembling procedure to be removed from the fixing surface is attached, the bundled wire is fixed on the fixing surface on which the information indicating the disassembling procedure is described. Since the fixing member is attached and detached and the bundle fixing member can be easily removed from the fixing surface, the recyclability of the bundle fixing member is further improved.
